Hello everyone, I have 2 TCL Miracle AC.
I would like to integrate them in Home Assistant, is there anyone who has done it to help me?

#

havent done it but what type of connectivity do they have? are they smart to begin with or not? how do you currently control them?

Hi! I control them through the controller but i want to do an automatation

#

I am trying to do a reverse engineering

#

is there anyone that can help me with that?

#

I want to use door trap in order to close the AC. Installing a smart plug is not optimal since cutting the power with that way can damage the outdoor unit of AC

#

any idea?

#

is the remote IR?

#

if so then an esp32 with an ir blaster might be the way to interact with it

#

you could add power tracking to help comfirm state

#

That would be a possible solution, but is there any guide to that??

#

Since the AC have wifi connection! I was wondering if it is easier to monitor the packets that closing the AC and send the corresponding packets with script from the HA

you can see if anyone has reversed engineered a solution using the wifi connection or do it yourself but its not a simple process. emulating the ir remote would be easier. if you look around you can find people that have done simalar things i am sure

#

so what is your suggestion for emulating IR do you have any guide?

#

you would probably have to tailor any guide to your exact remote and the IR codes it uses but an example would be something like this https://community.home-assistant.io/t/faking-an-ir-remote-control-using-esphome/369071

#

also it looks like someone reverse engineered the protocol a bit and its based on tuya
reverse enginnering documentation https://github.com/DavidIlie/tcl-home-ac
prototype custom integration https://github.com/DavidIlie/tuya-smart-ir-ac
youtube video explaining the above https://www.youtube.com/watch?v=A8ICsEnGfkg

David's solution is inadequate. It does not provide a clear explanation of how to integrate it into Home Assistant (HA). Additionally, the approach he uses is essentially a Man-in-the-Middle (MITM) solution. He observed the network traffic, and by placing a server in the network, it mimics the phone commands sent to TCL's cloud server and returns the desired packet to the AC unit.

In essence, the solution is overly complicated and resembles a home project suitable for a freshman studying at a computer science-related school.

I intend to implement a cost-effective and efficient IR-based solution, and I will update you with any developments.

Thank you in advance for your assistance!
